StampFly v1.1 is a programmable open-source quadcopter kit, an iterative upgrade of the StampFly series. The core improvement is the main control module upgraded from Stamp-S3 to the more powerful Stamp-S3A, with a newly optimized antenna structure design that significantly enhances wireless signal reception performance, resulting in a more stable remote connection.
The drone integrates a BMI270 six-axis gyroscope and a BMM150 three-axis magnetometer for accurate attitude and orientation detection. Paired with a BMP280 pressure sensor and two VL53L3 distance sensors, it achieves stable precise altitude hold and intelligent obstacle avoidance. Onboard buzzer, reset button, and WS2812 RGB LED are used for human-machine interaction and device status indication. It comes with a 320mAh high-voltage battery and four high-speed coreless motors, providing ample power output.
An onboard INA3221AIRGVR chip monitors real-time current and voltage. Two Grove expansion interfaces are reserved for flexible connection of various sensors and peripherals. The product is pre-loaded with a debugging program. When used with the Atom Joystick remote controller, it establishes wireless communication via the ESP-NOW protocol, supporting both manual and automatic flight modes, enabling features like fixed-point hovering and aerial flips. The complete firmware source code is open-source, facilitating secondary development and feature customization. It is suitable for STEM education, scientific research experiments, drone project development, and embedded learning training.
This tutorial will introduce you to using M5Burner to flash the factory firmware on StampFly & Atom Joystick, pairing, and the basic operation and indicators of the quadcopter.
Note
Charging Notice
Connect the battery to the charging slot of the Atom Joystick, then connect the data cable to the Atom Joystick to start charging.
Battery Maintenance
1. Do not discharge the battery below 3V per cell under load. 2. Do not store a fully charged battery for more than 3 days. For long-term storage, keep the voltage between 3.8V and 3.9V.

BMM150 Magnetic Interference
Products with magnets may interfere with the BMM150 magnetic sensor, causing abnormal readings. When used with M5 main controllers that contain magnets, the magnet must be removed, and the BMM150 sensor should be kept away from strong magnetic fields.
